getFields	array: Array, fields: Array	Returns an array of objects containing only the required fields
getOneField	array: Array, field: string	Returns an array of all the values of the particular field
searchByKeyField	array: Array, searchField: string, searchValue: string, reqFields?: Array	Searches the array for the given (key, value) pair and returns only the reqFields. If nothing is passed, the whole object is returned.
deleteByKeyField	array: Array, field: string, value: string	Deletes an item based on the (key, value) pair
